Purines - Uric Acid Testing
DefinitionUric acid tests are tests that are done to measure the levels of uric acid in blood serum or in urine.

PreparationThe uric acid test requires either a blood or urine sample.
- For the blood sample, the patient should be fasting (nothing to eat or drink) for at least eight hours before the test.
- The urine test for uric acid requires a 24-hour urine collection.
- The urine test does not require the patient to fast or cut down on fluids.
- Some laboratories encourage patients to drink plenty of fluids during the collection period.
Abnormal resultsThe lost secret of ankle gout the blood test is a level of uric acid higher than 12 milligrams per deciliter (about 4 ounces). Give yourself a momentary pause while reading what there is to read here on Uric Acid. Use this pause to reflect on what you have so far written on Uric Acid.
- Decreased excretion of uric acid is seen in chronic kidney disease, low thyroid, toxemia of pregnancy, and alcoholism.
- Patients with gout excrete less than half the uric acid in their blood as other persons.
- Only 10-15% of the total cases of hyperuricemia, however, are caused by gout.
- The information available on Kidney Stone is infinite.
- There just seems to be so much to learn about, and to write about on Kidney Stone.

BioThe completion of this article on Uric Acid Blood Levels was our prerogative since the past one month. However, we completed it within a matter of fifteen days!
Uric Acid is a Waste Product that Results from theBreakdown of purine, a nucleic acid. (Nucleic acids are the building blocks of DNA.) Uric acid is made in the liver and excreted by the kidneys. If the liver produces too much uric acid or the kidneys excrete too little, the patient will have too much uric acid in the blood. This condition is called hyperuricemia. Supersaturated uric acid in the urine (uricosuria) can crystallize to form kidney stones that may block the tubes that lead from the kidneys to the bladder (the ureters).
Lies About Purines, Uric Acid And Gout

The Uric Acid Tests are Used to Evaluate the Blood LevelsOf uric acid for gout and to assess uric acid levels in the urine for kidney stone formation. The urine test is used most often to monitor patients already diagnosed with kidney stones, but it can also be used to detect disorders that affect the body's production of uric acid and to help measure the level of kidney functioning.

Abnormally Low Uric Acid Levels May Indicate that thePatient is taking allopurinol or probenecid for treatment of gout; may be pregnant; or suffers from Wilson's disease or Fanconi's syndrome. This can be considered to be a valuable article on Uric Acid Kidneys. It is because there is so much to learn about Uric Acid Kidneys here.
The Laboratory Should Also be Notified If the Patient HasHad recent x-naturally cure gout: top 5 tips to treat gout naturally dyes. These chemicals increase uric acid levels in urine and decrease them in blood. Using great confidence in ourselves, we endeavored to write such a long article on Uric Acid Gout. Such is the amount of matter found on Uric Acid Gout.
Urine testPatients should be checked for the following medications before the urine test: diuretics, aspirin, pyrazinamide (Tebrazid), phenylbutazone, probenecid (Benemid), and allopurinol (Lopurin). If the patient needs to continue taking these medications, the laboratory should be notified.
Increased production of uric acid may result from eating foods that are high in purine. Increased uric acid levels due to overproduction may also be caused by gout, by a genetic disorder of purine metabolism, or by metastatic cancer, destruction of red blood cells, leukemia, or cancer chemotherapy.
Blood testPatients scheduled for a blood test for uric acid should be checked for the following medications: loop diuretics (Diamox, Bumex, Edecrin, or Lasix); ethambutol (Myambutol); vincristine (Oncovin); pyrazinamide (Tebrazid); thiazide diuretics (Naturetin, Hydrex, Diuril, Esidrix, HydroDiuril, Aquatensen, Renese, Diurese); aspirin (low doses); acetaminophen (Tylenol); ascorbic acid (vitamin C preparations); levodopa (Larodopa); or phenacetin. These drugs can affect test results. The sources used for the information for this article on Gout forums are all dependable ones. This is so that there be no confusion in the authenticity of the article.
Blood testReference values for blood uric acid vary from laboratory to laboratory but are generally found within the following range: Male: 2.1-8.5 mg/dL; female: 2.0-6.6 mg/dL. Values may be slightly higher in the elderly. It was with great relief we ended writing on Purine Metabolism. There was just too much information to write, that we were starting to lose hopes on it's completion!
Urine testReference values for 24-hour urinary uric acid vary from laboratory to laboratory but are generally found within the following range: 250-750 mg/24 hours. Maintaining the value of Uric Acid Gout was the main reason for writing this article. Only in this way will the future know more about Uric Acid Gout.
Certain Foods that are High in Purine May Increase thePatient's levels of uric acid. These include kidneys, liver, sweetbreads, sardines, anchovies, and meat extracts. We have also translated parts of this composition into French and Spanish to facilitate easier understanding of Uric Acid. In this way, more people will get to understand the composition.

RisksRisks for the blood test are minimal, but may include slight bleeding from the puncture site, a small bruise or swelling in the area, or fainting or feeling lightheaded.
